Long-term outcomes of aortic root procedures for heterogenous ascending aneurysm disease in bicuspid aortic valve syndrome.

Objective: Surgery for ascending aneurysms in bicuspid aortic valve syndrome primarily includes Bentall root replacement, aortic valve replacement with supracoronary ascending aorta replacement (AVRSCAAR), and valve-sparing root reimplantation (VSRR). Comparative analysis of long-term clinical and functional outcomes of these procedures is detailed.

Methods: From 1997 to 2017, 635 patients with bicuspid aortic valve undergoing root complex-focused procedures electively were stratified by valvulopathy (ie, aortic stenosis vs aortic insufficiency) and substratified into ascending or root aneurysm phenotype.

Selection of prosthetic aortic valve and root replacement in patients younger than age 30 years.

Objective: Long-term outcomes of prosthetic aortic valve/root replacement in patients aged 30 years or younger are not well understood. We report our single institutional experience in this young cohort.

Methods: From 1998 to 2016, 99 patients (age range, 16-30 years) underwent aortic valve replacement (n = 57), aortic valve replacement and supracoronary ascending aorta replacement (n = 6), or aortic root replacement (n = 36).

Predictors of Recurrent Aortic Insufficiency in Type I Bicuspid Aortic Valve Repair.

Background: Annular stabilization techniques in bicuspid aortic valve (BAV) repair include valve-sparing root reimplantation (VSRR), external subannular aortic ring (ESAR), and subcommissural annuloplasty (SCA). Unlike VSRR that offers neoroot creation, ESAR and SCA offer annular reduction only. We compared long-term functional outcomes to understand BAV repair durability.

Fate of remnant sinuses of Valsalva in patients with bicuspid and trileaflet valves undergoing aortic valve, ascending aorta, and aortic arch replacement.

Objective: In patients presenting with aortic valvulopathy with concomitant ascending aortic aneurysm, surgical management of the sinus of Valsalva segment remains undefined, especially for moderately dilated aortic roots. In patients with this pathology undergoing aortic valve replacement with supracoronary ascending aorta replacement, we assessed the fate of the remnant preserved sinus of Valsalva segment stratified by aortic valve morphology and pathology.

Methods: From 2002 to 2015, 428 patients underwent elective aortic valve replacement with supracoronary ascending aorta replacement.

Have hybrid procedures replaced open aortic arch reconstruction in high-risk patients? A comparative study of elective open arch debranching with endovascular stent graft placement and conventional elective open total and distal aortic arch reconstruction.

Objective: Open total arch procedures have been associated with significant morbidity and mortality in patients with multiple comorbidities. Aortic arch debranching with endovascular graft placement, the hybrid arch procedure, has emerged as a surgical option in this patient population. This study evaluates the outcomes of a contemporary comparative series from one institution of open total arch and hybrid arch procedures for extensive aortic arch pathology.

Retrograde and antegrade cerebral perfusion: results in short elective arch reconstructive times.

Background: Debate remains regarding optimal cerebral circulatory management during relatively noncomplex, short arch reconstructive times. Both retrograde cerebral perfusion with deep hypothermic circulatory arrest (RCP/DHCA) and antegrade cerebral perfusion with moderate hypothermic circulatory arrest (ACP/MHCA) have emerged as established techniques. The aim of the study was to evaluate perioperative outcomes between antegrade and retrograde cerebral perfusion techniques for elective arch reconstruction times less than 45 minutes.
